WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 498,939, dated June 6, 1893.

Application filed February 18, 1898. Serial No. 462,899- (No model.)

To all whom it may concern.-

Be it known that I, ZACHARIAS LOUDEN- BECK, a citizen of the United States, residing at Marengo, in the county of McI-Ienry and State of Illinois, have invented certain new and useful Improvements in Window-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to certain new and useful improvements in windows and it has for its objects among others to provide an improved construction of window having screens which can be readily put in or taken out without disturbing any part of the window; my

screens fill one sash except when used for ventilation. I get full benefit of the screens for one half of the window or less if desired by simply raising the lower sash. I have two independent screens, one of which is provided with spring stops upon which the other is designed to rest and which also serve to cushion the screen upon which they are secured.

Other objects and advantages of the invention will hereinafter appear and the novel features thereof will be specifically defined by the appended claim.

The invention in this instance resides in the peculiar combinations and the construction, arrangement and adaptation of parts, all as more fully hereinafter described, shown in the drawings and then particularly pointed out in the claims.

The invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this specification, and in which- Figure 1 is a front elevation of a portion of a window constructed in accordance with my invention. Fig. 2 is a horizontal section through the line 2-2 of Fig. 1, looking down, showing the spring stops on the lower screen frame. Fig. 3, is a vertical section. Fig. 4 is a perspective view of the lower screen fram e removed and its side strip also removed therefrom.

Like letters of reference indicate like parts throughout the several views in which they .appear.

This sash has attached to its' frame and is affixed thereto in any suitable manner; it may be a part of the sash or it may be an independent frame detachably affixed thereto by screws or any other means. To this screen frame is attached thewire gauze C which is held thereto by means of the surrounding strips b preferably of some thin metal through which pass the screws or nails 0; by this means the gauze can be readily removed when it is desired, as to replace it by new when the old becomes worn out.

The outer face of the lower cross bar of the screen frame is provided with a metal strip D which serves to take the wear as the screens are moved up and down.

E is a screen frame fitted to slide in the vertical grooves of the window as shown and this frame is also but about one half the thickness of the sash so that the two screen frames move in the same groove as the sash and the two occupy but about the same space as does the sash. This screen frame is providedwith a suitable knob or handle E by which it may be raised and lowered, and upon the rear face of itsupper cross bar there is secured a thin metallic wear strip F which is designed to rub against the wear plate on the lower cross bar of the other screen and thus prevent marring of the frames.

To the under side of the lower cross bar of the screen frame E there is secured at each end a spring stop G which extend outward beyond the frame of the screen as shown best in Fig. 2 and nearly to the vertical wall of the groove in which the frame is designed to work. These stops are seated in grooves or recesses in the bottom face of the screen frame and are preferably formed of spring metal with the one end secured to the frame and then the other and bent upon itself as seen and the free end designed to receive the upper screen frame as the same is lowered; these stops will also serve to cushion the lowerscreen frame as it comes toa stop. The advantages of such a construction and arrangement of parts as are above described will be apparent. The lower screen being arranged beneath the lower cross bar of the sash proper the two can be raised together when desired by simply pushing upward upon the lower frame. The two can be moved independently of each other when desired.

In order to facilitate the insertion and removal of the lower screen frame when desired I provide the same upon one or both of its side edges with a removal strip H which is held to the side of the screen frame in any suitable manner as forinstance by the screws 9 or other detachable means. In order to insert this frame in its proper position the strip is placed in the groove and then the frame placed in position and the screws screwed in,

thus holding the strip to the frame and by A this means holding the frame in position against displacement from the groove.

The improvements add but very little to the cost of the window and are such that they can be made by an ordinary skilled workman.

What I claim as new is The combination with the window frame and the sash and its screen, of the lower screen frame the two screen frames being adapted to slide in the same groove, and the spring stops secured to the lower cross bar of the lower screen frame and having their ends bent upon themselves and extended beneath the upper screen frame, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
